In order to ascertain the benefits from application of the ultrasonic vibration to precision grinding, the workpiece feed rate was set at a low value of 5 mm/min. Correspondingly, a large value of depth of cut is required to ensure material removal rate; hence, the value of Δ was set at 80 μm.
In ultrasonic machining, a tool vibrating longitudinally at 20 kHz to 30 kHz with an amplitude between 0.01 mm to 0.06 mm is pressed onto the work surface with a light force.. As the tool vibrates with a specific frequency, an abrasive slurry, usually a mixture of abrasive grains and water of fixed ratio (20% – 30%), flows under pressure through the tool-workpiece interface.
In ultrasonic machining, the tool moves vertically or orthogonal to the surface of the part and fluctuate at the ultrasonic frequencies, the vibrations generated by the tool will project micro-sized abrasive particles to the part at a high speed, the particles mix with water or other liquids to form a slurry, which flowing between tool and workpiece, helps to grind away material from the ...
Ultrasonic machining, also called ultrasonic drilling, is a subtractive fabrication process that uses high-frequency vibrations and abrasive particles to remove small amounts of material from a workpiece's surface.It is ideal for glass fabrication operations, as it removes surface material very slowly without compromising the substrate's crystalline structure.
